Giant Wall of Watery Doom
... Too soon... ami.
"They say the wave was 400 meters high when it hit the cities! Three billion dead, Gendo!"
Water, in large amounts and at anything above a modest velocity, is very dangerous stuff. Storm surges and flash floods claim hundreds of lives and cause millions of dollars in damage every year, while major disasters such as dam collapses
and tsunamis can cause widespread destruction.
When someone steps out of their house and sees a 200-foot-high wall of the stuff stretching on into the horizon and moving at a deceptively patient pace toward them it usually results in an intense Oh, Crap
Inversion of Soft Water
(or an aversion, as even being buried by an avalanche of fluffy pillows would likely be quite lethal if there were a few million tons of them moving at 70 miles an hour). Can occur when a character who makes a splash
really pushes himself to the limit.

- Gali, Toa of Water, pulled this off in a BIONICLE web serial. She usually just goes for bursts of water, but this time she decided the enemy was strong enough to warrant the of use very single drop of elemental energy she could muster. The wave was described as being "a thousand feet high" and destroyed every building in the land of Karzahni.
- In Sharon Creech's The Wanderer, the crew encounters a wave like this during a horrific storm. It's important later because Sophie remembers the wave as having been black, when according to everyone else, it was white.

- During the Matthew Good song Last Parade, specifically the lyrics
Like we're taking pictures of a tidal wave
On the shore, grinnin', a hundred feet away
- In "Suddenly There Is a Tidal Wave", the final song on The Wayward Bus LP by Magnetic Fields, the chorus goes:
The boys talk like they own the world
The women keep their stupid diaries
But suddenly there's a tidal wave
And everything is sucked out to sea
- Later in the song the chorus is repeated, twice, back-to-back. Three seconds later the music abruptly stops. (No similarity to a Three Second Silence.) Then—if you happen to be listening to the two-fer CD The Wayward Bus/Distant Plastic Trees—enjoy four-and-a-half minutes of silence, followed by the songs on the Distant Plastic Trees LP. Perhaps (analogous with "hidden tracks"), this qualifies as a HiddenAlbum?
- Was The Wayward Bus ever released, standalone, in any format? If not—and, let's say you're listening to The Wayward Bus—then you can be certain Distant Plastic Trees will follow.
- The band Great Big Sea took their name from an old Newfoundland folk song about the 1929 tsunami described below.
- Time Machine (Zaccaria) combines this with Time Crash, as the collision of Past and Future eras is represented by two tidal waves colliding to form a massive waterspout that dwarfs mountains.

- Yep, and also a Tsunami card.
- There's also a spell by the same name in Spell Compendium, as well as the Tsunami spell.

- The Forgotten Realms had the Tidal Wave spell, which was 75 feet high.
- Gali summons one of these and destroys the realm of Kharzani in BIONICLE.
- Happens in Chrono Trigger, as a result of a floating chain of islands crashing into the sea. Results are about as catastrophic as you'd think.
- In Chrono Cross, you visit the Dead Sea, a city that was frozen in time as it was being destroyed by these.
- Strago's "Clean Sweep" lore in Final Fantasy VI takes this form.
- As does the summon Bismark in the same game, and possibly some forms of Leviathan.
- Also the "El Nino" result of Mog's Water Rondo dance, which is the strongest water-based attack in the game.

- Castlevania: Order of Ecclesia: One of the bosses will produce some moai heads, then follow it up with a massive tidal wave. Make sure you don't destroy them.
- In Pokémon, the moves Surf and Muddy Water both use this trope.
- Happens twice in the World of Warcraft Cataclysm cinematic, at Booty Bay and Thousand Needles.
- One stage in Donkey Kong Country Returns has you taking shelter from these at regular intervals. Being exposed will kill you.
- Tsunamis are one of the earlier and constant threats in From Dust.
- This is one of a few reasons not to hurt the Chao - Chaos will get angry and cause one of these. The ancient echidnas learned that the hard way.
- This is how the aptly named Tidal Wave spell looks in the 2D games of the Tales Series.
- In the first level of Super Ghouls 'n Ghosts, giant tidal waves repeatedly rear up in the background while you're jumping across a series of platforms. Although the waves don't actually affect Arthur directly, they will wash away large parts of the terrain, killing you instantly if you're not standing on a "safe" part.
- In Final Fantasy XII, one of Balthier's Quickenings is a tsunami.
- At one point in Out of This World, Lester has to run from a watery Advancing Wall of Doom.
- In the Whateley Universe, Riptide is a side character. But when Chaka gets hurt in "Ayla and the Birthday Brawl" and Riptide gets really upset, and there's a lake handy, a badguy in a getaway van finds out there's nowhere to run.
- Real-life tsunamis are not as visually spectacular as the "wall of water" that many trope examples invoke: they're more like a very rapidly rising tide. However, the speed and force of the water is such that you do not want to be in it.
- Indeed, the majority of real-life tsunamis could be seen as an aversion of the trope. They most often look very tame when they are approaching the shore, not much different from a normal wave. They are extremely deceptive, though; rather than stopping at the shore like other waves, they just keep on going and going inland without stopping...
- The 2011 Tohoku earthquake and tsunami is possibly one of the largest, most widely youtubed disasters in history.
- In Alaska, a piece of a mountain fell into Lituya Bay, and it is estimated that the resulting splash was nearly a half mile (800m) high.
- The only tsunami known to kill people in Canada occurred in 1929, off the coast of Newfoundland. An earthquake in the Mid-Atlantic Ridge created a wave of water that swept houses completely off the land. The locals called it the "great big sea".
- The 2004 Indian Ocean tsunami was caused by an earthquake that uplifted a 100 mile long section of sea floor, releasing a titanic amount of energy.
- The 1700 Cascadia earthquake occurred off the coast of what's now Washington and British Columbia, devastating that coastline with waves up to 30 meters. It existed in the historical record only in Japan, which had an orphan tsunami with no apparent cause at the same time. It wasn't until 300 years later that physical proof was found of origin in the Pacific Northwest.
- Sometime in February 1933, the US Navy oil tanker USS Ramapo was steaming through a nasty Pacific gale when she encountered a massive wave. Fortunately, she escaped with minor damage. Geometric calculations, however, showed the wave to have been 112 feet tall. To this day, it remains the tallest wind-driven wave ever recorded.
- Estimations by oceanographers suggest that the tallest height possible for a wind-driven wave is 198 feet. Of course, it would take a freakishly rare combination of events and geography to produce such a monster; but still, a wave of that size could severely damage or even sink any ship unfortunate enough to encounter it.
- One analysis of the Thera eruption in the 17th Century B.C.E. states that in Turkey, "two peninsulas jutting into the Aegean Sea confined the wave ... building it higher and higher and ultimately funneling it thirty miles inland. To penetrate so far, it had to be eight hundred feet tall when it hit the shore." Thera is almost a hundred miles from the peninsulas mentioned, and there are other islands in the way which would've robbed the wave of some of its force ... but it was still 800 feet tall.
- During the end of the last ice age, an immense ice dam in what is now Washington state collapsed under the weight of the water behind it, causing a series of devastating floods across the eastern part of the state — the most powerful of these generated the equivalent of 4500 megatons of TNT.
- The volcano on La Palma in the Canary Islands could cause one; an eruption could potentially send part of the island sliding into the Atlantic, causing a MEGAtsunami that could obliterate the east coast of the United States from Florida to Maine.
- Rogue waves. They can be up to 35 m high (yup, that's 115 feet) and they are preceded with a trough so deep and steep as described as "like a hole in the ocean". Their existence has been doubted, but they do exist. A rogue wave is steep and resembles a vertical wall of water, and can sink even an ocean-going ship, nevermind yachts and fishing vessels.
- For a long time The Biblical Flood has been considered legend or myth and without evidence, but there are indications it was indeed based on an actual event.
- The leading hypothesis that the Flood was inspired by the flooding of the Black Sea at some point around 5600 BCE, which presumably would have looked a lot like this to the people present.
- The Burckle Crater in the Indian Ocean, if indeed it turns out to be a crater, is hypothesized to have caused waves up to four kilometers tall when the object that created it hit, which would have hit most of the cradles of humanity at the time.
- Tsunamis caused by underwater/into-water landslides are the largest and most powerful type after impact-generated tsunamis. Both are termed "Megatsunamis", and there have been several in recorded times, the most recent being in 1980 with the eruption of Mount St. Helens and its avalanche into Spirit Lake. Several areas are likely to produce a major landslide and megatsunami in the future, the most alarming being at the Hawaiian Islands, where a large chunk of the Big Island is slowly cracking away from the rest of the island. For another potential example, see above.
- The biggest tsunamis, speaking of which, are actually caused by meteorites crashing into the ocean.
- For example, the asteroid that killed the dinosaurs was thought to have created megatsunamis several kilometres high that were large enough to completely submerge islands as large as Madagascar.
- Sometimes, such tsunamis can take place in the least expected of places. In Vajont, Italy - in the mountains half a kilometer above sea level and nearly 100 kilometers from the coast - an entire mountainside (270 million cubic meters) collapsed into a reservoir half the size (shielded from a valley by a 200 meter dam). The dam itself withstood the pressure just fine, but the displaced water flushed over in a 250 meter-high wall of water and rolled through the valley beneath in a gigantic wave, destroying several villages and killing 2000 locals. It was the biggest man-made tsunami of all times.
- Less extreme than the others here, but in 1952, the English village of Lynmouth was devastated by a flash flood that swept away houses, bridges and a lifeboat station as well as causing the collapse of a lighthouse. The wall of water was "only" about fifty feet high and carrying tree trunks and boulders.
